@WebworkrNet I'm going to close #1320 and #1322 and possibly merge them with this one. Please try to open multiple changes for a same company on the same PR, since the system would not be aware of the other PRs and would overwrite information.

Also, Aras Kargo seems to have its own process and form at http://araskargo.com.tr/en/neuralnetwork.aspx?type=1723 - I think it should go on its own entry, what do you think @baltpeter?

Edit: Actually, just saw #1332 - we can probably close this PR too.

@fm I haven't looked into this but since @mal-tee has already opened #1332, he might have a reason to keep some of them open. So, he can better answer this than me.

I don't quite remember why I left these open. Feel free to add them to the issue. The issue was just my attempt at bringing some structure into this. :D

Since this has been stale for over a year, I have added this to #1332 and will close the PR.
